Hi adil,

For this issue, I recommend to provision the WSS Usage Application Proxy using the following PowerShell commands to see if the issue still occurs:

$UP = Get-SPServiceApplicationProxy | where {$_.TypeName -like "Usage*"}

$UP.Provision()

In addition, as this issue can be caused by many reasons, I recommend to check ULS log to get more detailed error message for further research.

Here are some similar issues for your reference:
